ABSTRACT:
A gasoline dispensing nozzle for discharging gasoline into receiving vessels and for removing vapors therefrom through a vapor removal line is provided with an automatic shut-off device that terminates the delivery of gasoline in the event liquid gasoline flows into said vapor removal line. The shut-off device comprises a sensing orifice disposed at the end of a flexibly mounted tube within said vapor removal line, which tube leads to a passageway extending into the housing of said gasoline nozzle and terminating in a chamber that contains a conventional, diaphragm-operated, trigger mechanism for closing the main nozzle valve. In operation, no matter which way the nozzle is inserted into a gasoline tank fill pipe, the sensing orifice, by gravity, will fall to a position such that, if gasoline flows into said vapor removal line, it must also flood the sensing orifice. When gasoline enters the sensing orifice, the diaphragm-operated trigger mechanism, responding to a suction created by the flow of gasoline through a conventional venturi within the nozzle housing, releases the spring-to-close main nozzle valve.
